Software RAID 5 and it's variants are the opposite of performance. If
you want performance with redundancy then use RAID 1+0. Better to use
ZFS or Btrfs with mirrored data and metadata. This is faster and easier
to manage than LVM2 and mdadm.

What do you mean by "web interface"? Access to shared files systems?
Configuration? Something I missed?

FreeNAS isn't "targeted" toward FreeBSD. It is FreeBSD.

There's nothing wrong with the CDDL. It's a perfectly valid free
software license. Regardless, FreeNAS also uses UFS and has plugins for
other file systems, and it has software and fake RAID systems.

I advise against doing this with RAIDed disks. You can run into
problems with spinup taking too long. This will fault the RAID set.

It's slow, clunky, and not worth the hassle. Use ZFS or Btrfs instead.
